kinetics, rice husk, mechanism, lignin, decomposition, silicon dioxide


The study addresses the problem of using recycled materials for the production of a wide range of diverse products; in this context, the paper investigates the extractin of amorphous silicon (IV) dioxide from rice waste, i.e. rice husk, which differs in its chemical composition from all other cereal crops by a high content of silicon dioxide. Amorphous silicon (IV) oxide is widely used in electronics, medicine, food industry, cosmetology, paintwork materials manufacturing, and other industries. Amorphous silicon(IV) oxide has to meet various requirements, the main ones being amorphous structure, degree of purification, and particle size. A derivatographic method of analysis is used to study the non-isothermal kinetics of rice husk residue thermal decomposition. According to the results of derivatographic, chemical, and phase analyzes, a method for amorphous silicon (IV) oxide extraction by thermal decomposition of rice husk after the lignin removal has been proposed. The values of relative activation energies and the pre-exponential factors of the reactions have been calculated. A mathematical model characterized by a system consisting of three first order differential equations and four algebraic equations has been designed. Through the use of the proposed model, the time response characteristics of the process have been studied.
